My two cents worth here. Go with 5 gallon buckets. Many purchased from the local donut shop at $1.25. My variation on Mylar bags and oxygen absorbers — a chunk of dry ice, about 3×4 inches. With this on the bottom of the bucket and little piece of paper towel over it, pour in rice or beans or wheat or corn or a mixture of things. Put the lid on, but do not snap it tight. Wait a few minutes until the bottom of the bucket is not real cold and snap the lid on. Dry ice, which is CO2, forces out the air in the bucket. I recently opened rice and a mixed container which had been sealed five years ago. Everything was fine. Obviously we did eight or 10 of these buckets at once. Got dry ice from the local grocery store. Be sure to wear gloves when handling it.
Freeze-dried food is nothing new. As early as the 13th century, the ancient Quechua and Aymara people of Bolivia and Peru pioneered a form of the process by exposing potatoes to the freezing temperatures of the Andes overnight, then drying them in the sun. In 1937, Nestlé used industrial technology to create the world’s first freeze-dried coffee, and in the 60s and 70s, the US military shipped freeze-dried food rations to the troops in Vietnam.
One of the biggest obstacles for new preppers is building a stockpile of food and supplies in case of emergencies. Having enough money to reach a critical mass for the stockpile can take years, causing frustration and burnout. To combat this problem, a lot of preppers turn to couponing, and rightly so. However, a lot of preppers also remain skeptical of couponing.
